در این مقاله، مطالعات مدلسازی دینامیکی سیستم تقطیر غشایی تماس مستقیم در هندسه صفحه تخت ارائه شده است. ابتدا با اعمال موازنههای جرم و انرژی، معادلات توصیف کننده رفتار دینامیکی فرآیند تقطیر غشایی تماس مستقیم در هندسه تخت محقق گردیده است. در ادامه به منظور حل عددی این معادلات در بستر نرمافزار MATLAB، از روش خطوط استفاده شده است. جهت اطمینان از نتایج حاصل از مدلسازی عددی، نتایج بدست آمده از مدلسازی با نتایج تجربی موجود در مقالات با زمینه تحقیقاتی مرتبط، مقایسه و صحتسنجی شده است. نتایج حاصل از صحتسنجی، نشاندهنده حداکثر خطای میانگین 05/4 درصد بین مدلسازی و نتایج تجربی است. همچنین نتایج بدست آمده از مدلسازی مفروض (برای پارامترهای موثر بر عملکرد سیستم تقطیر غشایی تماس مستقیم)، نشان میدهد که تغییرات دمای جریان گرم غشاء بیشترین تاثیر را بر روی شار نفوذی به سمت سرد غشاء را دارد. به نحوی که افزایش 10% در دمای جریان گرم غشاء شار نفوذی از غشاء را 8/49% درصد افزایش میدهد.
